Is there an easy way to selectively delete groups of caches from a Garmin GPS?

When I travel to different cities, I'll create a new GSAK database, and then upload all the caches for that zip code. But in the GPS, they simply merge with the other waypoints, and the GPS waypoint management options are Delete One, or Delete All.

How do you all migrate different groups of caches on and off your GPS?

I've also noticed that when you upload FROM the GPS to GSAK, it loses the state ID, which is unfortunate...

Only if the group of caches are grouped by a particular symbol. Find>Waypoints>Menu>Delete by symbol...

Otherwise, if you attach your GPSr to a laptop and upload all waypoints into your waypoint manager, delete waypoints on your GPSr, and resend, it is possible. Not cute or easy._________________The Lucid Network (tm)-- More Bars in More Places!

I figured you would, but I didn't post it right away because I"m at work and don't have my GPS with me to test the steps to make sure I'm giving false directions.

The Twins Radio Network file you got is only the .csv file, which is what POI Loader sends to your GPS. On its own, it wont' do anything. You can open it in spreadsheet program or text editor to see how it's built...pretty simple stuff. I created that one in about 10 minutes.

In GSAK, you must save the file in .gpx format, which is the other format POI Loader can handle. With the version I linked to, to get separate databases, you name the file the same as you want the database name to be. Then use POI Loader to transfer to the GPS, then put the GPS into USB Storage Mode (Under settings) and go into the file structure and rename the poi.gpi file as something you'll remember, such as TwinsRadio.gpi

Then upload the next file, and so on. IF you don't rename the file, it will get overwritten. IT doesn't matter what you call it...the name of the database is tied to the name of the original file. So if the file on your PC is Twins.csv, then you upload and rename it TwinsRadio.gpi, when you get into the custom POI in your GPS, that database will be called "Twins"

Once you get that done, go to your find menu, then Custom Points of Interest, and it will list the closest POI from ALL databases. Click the lower left button (Menu?) and you'll have the option selecting your POI database. If you only have one database in the GPS, you wont' see this option.

There's a beta version of POI Loader that will allow the separate databases directly, but I haven't tried it yet.

You can also do this directly to your microSD card in a card reader...no GPS need be connected.

I still load up waypoints for caches in the area, but I've loaded the entire state as POI's in case I have to go out of town on short notice.

I guess I pretty much stepped it all out anyway. If you have any other questions, let me know.

5savages - this is great - thanks for taking the time! (It explains why I don't see those radio stations) I'll give it a try.

How did you come up with the whole state in a POI database? That seems like a really useful thing...

Using the Pocket Queries from geocaching.com, I get updates on all caches in the state every week. I then export a gpx file from GSAK for use as a POI database. I recall that in the screen where you set up the name of the waypoint or POI, there's a field for comments. I set GSAK up to put the hints in there. I think the code is %hint . What I'll probably do next time is set it up to put as much of the cache description as possible in there.

One other thing I do with GSAK that I find handy is to set it up so the name of the waypoint tells me the size of cache, type of cache, and difficulty/terrain rating. I follow that with the "smartname" or whatever they call it, and limit it all the the number of characters my GPS can handle. The type, size, difficulty, and terrain all take just 1 character each, so on my Legend, it leaves 6 characters for the smartname, and on my Legend Cx I think it leaves 10 characters.

A one character field for the ratings can get confusing...it uses 1 for 1, 2 for 1.5, 3 for 2, 4 for 2.5...etc.

Fer instance, If a cache s a regular container, Traditional type, with a 2/5 rating, the first 4 characters would be RT39xxxxxx. A multi micro 1/2 would be MM13xxxxxx

POI can be frustrating in the respect that they don't pop up on your screen until you're zoomed way in, and they don't list the name unless you hover over the dot, as I recall. That's why I still use waypoints locally, but have the POI available for any hint that I might need. On the other hand, they don't clutter the screen when you're using the GPS just for regular ol' navigation.

Finally got around to trying it.. This is a great idea! Thanks!!

This might be just perfect. The screen clutter is annoying. The metro usually looks like a big blob... I can't see any of the streets.
